International Doom



International Doom is a small, functional and simple source port, created with help, efforts and bits of code from people around the world. It is based on Chocolate Doom and Crispy Doom, with significant additions from Doom Retro.

International Doom was previously known as "Russian Doom", but was renamed in response to the Russian invasion of Ukraine.
